Nano waterproof agent is a kind of waterproof coating material manufactured by nanotechnology.It is composed of nano particles with very small particle size, which can fill the micropores and microcracks on the surface of the material at the micro level, thus forming a waterproof barrier.
Nanometer waterproof agent can be applied to the surface of various materials, such as textiles, leather, wood, stone, metal, etc.It can effectively prevent moisture from penetrating into the interior of the material, thus playing a waterproof role.In addition, nano waterproof agent also has the characteristics of wear resistance, high temperature resistance, corrosion resistance, etc., which can improve the service life of materials.
Nano waterproof agent is widely used in construction, automobile, aerospace, electronics, etc.In the field of construction, nano waterproof agent can be used on roofs, walls, floors and other surfaces to prevent water infiltration from causing damage to building structures.In the automotive field, nano waterproof agent can be coated on the body surface to prevent rain, mud and other erosion of the body.In the electronic field, nano waterproof agent can be applied to the surface of mobile phones, computers and other equipment to improve the waterproof performance of equipment.
In general, nano waterproof agent provides a durable waterproof solution by utilizing the characteristics of nanotechnology, which can be widely used in various fields to protect materials from water erosion. Description of nano waterproof agent: Nano waterproof agent has the properties of waterproof, anti weathering, anti stripping and chemical corrosion resistance, and is widely used in the protection of various concrete, stone, wood, etc.When it is coated on the substrate, it can evenly penetrate into the microporous wall, and form a very thin hydrophobic film on the surface and inside of the substrate to achieve the purpose of waterproof. Distinctive features.Nano waterproof agent: potassium methylsilicate waterproof agent made by special process.Its oxygen ion content is close to zero, which is different from the traditional production process. It is not only non corrosive to the reinforcement, but also has the functions of moisture-proof, anti-seepage and air permeability.Easy to use: direct spraying (especially for leakage of external wall, if it is impossible to re lay, use the waterproof effect of spraying. It can also be made into waterproof mortar with cement as rigid waterproof. It has special functions and wide applications. ① Waterproof performance. If a waterproof coat is worn on the treated wall, the rain will fall naturally in the form of water drops, like lotus leaves, while the wall is always dry, which can effectively prevent mildew and efflorescence. ② With good air permeability, it can release moisture from the wall, just like the skin of healthy people, so it is also called respiratory waterproof coating. ③ The moisture-proof and mildew proof effect is remarkable, but the wall surface does not grow moss. Once the building surface is treated with this product, it can keep the interior dry in the external humid environment, especially suitable for the surface treatment of decorative coatings such as grain depots, residences, archives, libraries, etc., which can greatly improve the waterproof, color retention and pollution resistance of the coating, and can be used on the joints of ceramic tiles and mosaics,Because of its low water absorption, it will not store water and freeze in winter, resulting in expansion, which can prevent the peeling of tiles and mosaics. It can be used on natural stones such as memorial steles to prevent the growth of moss and keep the surface clean. ④ It has strong durability and weathering resistance. The waterproof agent can penetrate into the wall to a certain depth, so it is less affected by ultraviolet radiation and atmospheric aging. It can effectively prevent rain wash when used in gardens, ancient buildings, red, yellow and pink walls, stone statues, steles, etc., and maintain its original color. After being washed by natural rain, it is dust free, which can effectively prevent pollution, achieve anti-corrosion, weathering resistanceThe purpose of protecting cultural relics.This product has been successfully applied to the waterproof and impermeable wall, and is a new type of functional wall waterproof and impermeable building material in China. Potassium methylsilicate.Product introduction: This product needs to be diluted with water.It is used for the treatment of stone, tile, ceramics, cement mortar, perlite, gypsum, fiber gypsum board and other materials, especially porous materials, which can produce surface waterproof and reduce water absorption.It is permeable and absorbable, and can maintain the natural appearance of the substrate without changing the original color and appearance of the substrate.It can react with CO2 or other acidic compounds in the air to form an insoluble mesh waterproof and breathable film on the surface of the substrate, which has the advantages of waterproof effect, anti-seepage, moisture-proof, rust resistance, pollution resistance, etc. to prevent moisture from being absorbed into the substrate, thus reducing the peeling caused by freeze-thaw and weathering and increasing the service life of the substrate.This product is simple in construction, low in cost, durable in effect, wear-resistant, scrub resistant, high and low temperature resistant (- 50~150 ℃). usage method: 1. Clean the surface of the base material before use. If there are cracks, fill them with putty or cement slurry. 2. Before construction, the substrate surface can be slightly wetted for absorption. 3. When using, dilute the waterproof agent stock solution with water in the proportion of stock solution: water=1 ∶ 18~20 to 3% or lower concentration.If it is necessary to use 3% concentration for experimental verification, high concentration will lead to the formation of white residues on the waterproof surface.After painting, the surface to be treated shall be naturally dried, and the second coat shall be painted before the surface is dry.If it is used for surface protection treatment of stone and ceramic tile, wipe off excess liquid with soft cloth 5~10min after construction, and maintain it for at least 24h without touching water. 4. Theoretical consumption after dilution: 8~10m2/L. The waterproof agent has the advantages of being odorless, nonvolatile, nonflammable, good weather resistance, and no corrosion to reinforcement.There is also micro expansion, which can compensate the shrinkage of mortar and concrete;It can be constructed on wet substrate without affecting the bonding of waterproof layer and substrate, and the construction operation is simple and flexible;Convenient transportation, safe construction and low cost. Application principle of nano waterproof agent: nano waterproof agent is alkali activated chemical penetrant. According to the American test report, the alkali contained in a piece of concrete is at least 361 times that of the surface area, so it is not only very effective for water-based permeable crystalline inorganic waterproof agent to penetrate into concrete and react chemically with alkali,And its products become a permanent part of the concrete rather than the surface coating.At the same time, the special catalyst in the water-based permeable crystalline inorganic waterproof agent urges it to penetrate the concrete surface or the aggregate in it and look down for water to react.
